Patented Nov. 6, 1934 UNITED STATES PATENT OFFIQE 6 Claims.

, My invention relates to holdersand relates particularly to a holder for collapsible reservoirs, in which such articles as vanishing cream, cold cream, facial cream, shaving cream of thenclather type, ointments for the application to the skin, shoe polishes that come in ointment form, Photographers paste, body deodorants, tooth paste, etc., are sold, but may be used with any collapsible reservoir containing plastic or fluid material which one may wish to apply to a brush surface.

It is necessary now to squeeze the material out of the reservoir or tube, after removing the cap thereon, to a conveyor such as a piece of cloth, paid, the fingers, brush, etc., and from the conveyor to the final surface. The collapsible tube is set to one side and then the cap therefor is replaced over the opening when suificient material is used. Since the cap is small it is often.- t-imeslost or misplaced and thereby causes in.- convenience, since the contents of the tube are hardened by contact with the atmosphere, or the contents are unnecessarily expelled.

Usually the particular reservoir is placed amongst many other reservoirs and jars andtime is unnecessarily wasted searching for the particus lar. reservoir. 7

It is, therefore, an object of .my invention to provide a supporting frame for a collapsible reservoir which may be attached to a wall and is always available for use.

Another object of my invention is to, provide the lower end of the frame with jaws for grip,- ping opposite sides of the .discharge spout of the reservoir.

Another object of my invention is to provide the gripping jaws with a. wire spring whereby various size spouts may be utilized with the same container or holder.

A further object of my invention is to provide a valve or closure for the discharge spout of the tube, which closure is normally held in closed position to prevent air from contacting with and hardening the contents adjacent the discharge opening.

A further object of my invention is to provide a key ejector means whereby the tooth pasteor shaving cream can be readily expelled fromthe reservoir without removing the latter from the holder.

A further object is to construct a reservoir holder which may be separated to provide an easy and rapid means to replace the spent reservoir.

With the above objects in view my invention consists of a. fixed frame and a separable frame wherein a collapsible reservoir for tooth paste, shaving paste, etc., is held and one end of the reservoir is connected to a mechanical ejector, which progressively advances from the closed end of the reservoir to the spout, whereby the contents may be expelled at a rate under the absolute control of the operator and whereby the material of the tube will be completely expelled, and closure valve means to control the opening of the tube.

Other objects of this invention are to provide an improved device of the character described, that is easily and economically produced, that is sturdy in construction and which possesses a maximum degree of efficiency and .of accuracy.

With the above and related objects in view, my invention consists in t e details of construction and combination of parts, as will hereinafter be more fully described, when the description is read in conjunction with the following drawing n Which:

Figure 1 is a perspective view of my holder having a' collapsible reservoir therein;

Figure 2 is a perspective view of the bracket attached to the fixed sectional frame;

Fi ure 3 is a fragmentary perspective view of. the wire sprin on the base;

Figure 4 is a fragmentary perspective view of a modifiedjstructure for holding the separable frames together; and

Figured is a fragmentary perspective view of a modified structure whereby the cap for the reservoir is held Referring to the drawing, 1 show a collapsible reservoir holder comprising a fixed sectional frame A; an oscillatory sectional frame B complementary to the frame A, which permits the easy replacement of a spent reservoir; a manually controlled valve. and lock C, that controls the egress of the contents of the reservoir and which also holds .the lower portion of each of the frames together; and a key D to expel the contents of the reservoir R. r

The fixed frame A is composed of. side rods 10 and 12 placed in a vertical position. The upper ends of the bars are bent to form inwardly extending arms which extend into the ends of one side of a connecting tube 14, which tube connects the upper ends of frames A and 13 together. The lower ends of the bars 10 and 12 are welded or otherwise fastened to the sides of a base plate 16. Attached to the rods 10 and 12 are a plurality of semi-circular strengthening and supporting cross-arms 18 and 20.

A suitable wall bracket 22 is attached to the arms 18 and 20 for maintaining the device against a wall.

The oscillatory sectional frame B, constructed similarly to the frame A, is composed of vertically extending side rods, 26 and 28, bent at their upper ends to form inwardly extending arms which extend within the second side of the connecting tube 14. The lower ends of the rods are welded or otherwise fastened to the sides of a base plate 30.

The base plates 16 and 30 are constructed so that they are positioned in the same plane and when so positioned semi-circular sections 32 and 34 cut at their circumference form an opening 36 for the discharge nozzle of the reservoir.

To secure the nozzle of the reservoir in a fixed position and to accommodate various sized nozzles, a spring wire 38 is attached to the base plate 16, so that a portion of the spring crosses the semi-circular opening. A similar spring wire is positioned in base 30.

Each spring wire 38 is held and laid in notches 42 and 44 in the base plates 16 and 30.

The discharge of the material from the reservoir is controlled by means of a valve 46 having one end pivotally connected to one base plate 16 and having an extension 48 thereon which partially encircles a stud 50 in the base plate 30. A lever 52 is, also, attached to the valve to permit ease of operation.

To provide for ready removal of the reservoir for changing, it is to be observed that the bottom portions of the frame section may be swung outwardly about the connecting tube 14 as a pivot.

The vertically extending rods 10 and 12, 26 and 28 are placed sufiiciently close to one another to form a plurality of guideways for the key D which slidably and rotatably moves in the guideways. The key has a slot 54 therein which retains the closed end of the reservoir and when the key is turned the contents of the tube are forced through the discharge opening.

My invention operates as follows:-

The bracket 22 is attached to a wall or other suitable support. The key D is attached to the closed end of a reservoir R and the frame section B is moved outwardly. The spout of the reservoir is engaged by the wire spring 38 and the frame B is then closed, with the key D engaged between the rods 10-26, and 12-28, and the valve and lock C engaging the stud 50. To expel the contents of the reservoir the valve 46 is moved out of engagement with the spout and the key D is turned.

In Fig. 4, I show a modified structure for holding the separable frames together, that consists of a latch having one end fastened to a side of the base 16 and the other end hooked to engage a stud 62 on the side of the base 30.

In Fig. 5, I show a modified structure for covering the spout opening of the reservoir by an enlarged cap 64, which loosely fits over the spout.

. A spiral spring 66 rigidly fastened at one end pulls the cap 62 against the sides of the spout, thereby there is no necessity for screwing a cap in place.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting, as the invention may be variously embodied and the scope of the invention is to be determined as claimed.
